Good grief, usually it's because of a hairpin nat. People do that to themselves. They damage their own L3 networking and then decide that they need to damage also their entire DNS as a workaround.
It's a regular mind virus, because it's easy to implement split-horizon DNS but enormously expensive to remove it. People get used to it on one company and go and spread it on another company.
Just do a snat+dnat. These networking boxes are so expensive because they are meant to handle it, so let them do their job already. Or go IPv6 and get rid of DNAT altogether.
